LIGHTING FIXTURE WITH DISCHARGE BULB FOR VEHICLE
Document Type and Number:
Japanese Patent JP3854421
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To enhance a shielding effect of an electromagnetic wave in a lighting fixture for vehicle of which light source is a discharge bulb, to reduce the number of parts of the lighting fixture, and to attain simplification of assemble work thereof.
SOLUTION: In a lighting fixture for vehicle having a connector 11 which is mounted on and demounted from a plug 50 of a discharge bulb 5 that is supported by a reflector 3, a contact terminal part 153 is arranged which is electrically connected to a conductive membrane covering the reflector 3 at one part of a circumference of the reflector 3 where the connector 11 is mounted, and a conductive cover 21 is integrally provided at the connector 11 to cover the connector 11 such that the conductive cover 21 is brought into contact with the contact terminal part 153 under such a condition that the connector 11 is mounted on the plug 50. When the connector 11 is fitted to the plug 50, the conductive cover 21 is automatically electrically connected to the contact terminal part 153 which is electrically connected to a conductive membrane of the reflector 3 so as to exhibit a shielding effect, and accordingly an independent shielding parts is made needless and also its assemble work is made needless.
